Israel has not made any commitment to Washington not to attack Iran’s nuclear facilities during its negotiations with the West, Defense Minister Ehud Barak emphasized Tuesday morning.

In an interview from Colombia with Army Radio Barak said, “I do not believe the efforts of the international community to stop Iran’s nuclear program will bear fruit.”

“The time spent in this process is very precious,” he continued.

In a separate interview with Israel Radio, the defense minister reiterated that Israel did not believe the talks would lead to the desired solution, but added that he would be pleased to learn that he is mistaken. He said that the talks must lead to a clear outcome – a halt of Iran’s nuclear program.

He also stated that postponing the talks by five weeks presents Iran with a prize, and the opportunity to continue to develop its nuclear program.
